Home/Technical Glossary/ACF (Anisotropic Conductive Film) ACF (Anisotropic Conductive Film) Anisotropic conductive film (aka “ACF” or “ACF Tape”) is a lead-free, environmentally friendly interconnect system, generally found in tape form and commonly used when ACF Laminating and ACF Bonding processes as in LCD (liquid crystal display) manufacturing to make the electrical and mechanical connections from the electronics to the glass substrates of the LCD. The material is also available in a paste form referred to as anisotropic conductive paste (ACP), and both are grouped together as anisotropic conductive adhesives (ACAs). For more information, take a look at our paper on Conductive Adhesive Bonding.
